Specification of Letters atent.

` Patented Mar. 18, 1913'.

To all whom it' may aendern' di Be it known` that .I, ELISHA B. WRIGHT,a citizen of the United States, and a resident of St. Helena, in thecounty of Napa and State of California, have invented va new andImproved BicyclelPump, of which the following is a full, 7clear/andexact description. .Y

This invention relates togimprovements in bicycle pumps, and has for anobject to.,

provide an improvedpump and su orting devices adapted to hold the pumpfoifitting in a proper position on the 'bicycle frame for readyoperation at all times.

A further object of the invention is to provide' a plurality ofretaining. members and a pump structure on a bicycle frame so 'that thepump will be continually in position for operation but out of the way othe operation of the vbic cle.

In carrying out t e objects ofthe invention, an encircling clip isprovided for the upper bar and lower bar ofa bicycle-frame provided withsuitable interlocking ret-aining means designed to engage apump. Thepump is adapted to beuniversally pivoted to the lower clamp and isusually notremoved therefrom, while itis easily disconnected Afrom theupper clamp so as l,to be. operated.` A hose is connected to the pumpand is arranged so as to -be'yeasily connected with the valve -or either.ofthe bicycle wheels when it .isldesired to pump up the tires thereof.Y

A practical embodiment of the invention is represented in theaccompanying ings forming a art'of this specification, in

--which similar c aracters of'reference indicate corresponding parts inall the views.

Figure 1 is a fragmentary side view of the front of a bicycle,show1ng anembodiment of thefinvention a plied'thereto; Fig, 2 is k"an enlargedsectional view through a` mnp and associated partsn embodying theinvention; andFig. 3 1s a top plan view of the pump and clamp shown 1nFig. 2.

Referring to the accompanying drawings by numerals, 1 and 2 indicate thetop and lower-bars of a bicycle frame, and 3 the front tire of thebicycle which .is provided with the usual valve structure 4, to which aflexible tube 5 may be connected whenever I desired. The flexible tube 5is connected at 6 to a pump 7 'when the pun-ip is being used for pumpingup the tire 3. If desired to pump up the rear tire,` all that isnecessary piston 10 provided with the usual washer.

, 1, or to any other position, without relroving Application mea May s,1912. serial N6. 695,855.

is to remove the tubefrom the valve of the front tire and connect thesame with the valve ofthe rear tire. Thepump 7 is formed with an outercasingy 8, a piston rod 9, a

The piston 10 is adapted to be reciprocated back and forth in thecylinder 8 in the usual manner for forcing air out of the valve 6, thevalve 6 being of the usual construction, namely Aa check valve. Thecasing 8 is pro` vided with a base 11 having an extension 12 connectedtherewith in any desired manner. The extension 12 is provided with'aplurality "df -resilient clamping members 13 70l adapted to fit over aball 14 connected to the clamp 15.' The clamp 15 is held in place byV asuitablebolt 16 and may be adjusted f to any desired place on the`^ba12.v By arranging the arms and fingers 13 over a ball 75 14, the pump 7is substantially universally connected with the clamp 15 and cannot bereadily removed. The outer end of the pump is provided with the usualupper end or covering 1 7 and with a handle portionx 18 A30 connected tothe piston 9, the upper end being provided with the usual aperture foraccommodating thepiston 9 in its back andA i forth movement.

When the pump 7 is in use the same is moved from the position shown inFig. 1 to substantially the positionshown in dotted lines inFig. 1, andthen the piston 10 oper-. ated inthe usual manner. After ,the operatoris through using the pump the same is forced back to the position shownin Fig. 1,

vwherein v,theingers 19 snap overthe upper part ofJ the pump andespecially over the handle 18. The fingers 19 lare of resilient materialand permit the pump to be moved into engagement and from engagement"whenever desired. Preferably the 'fingers 19 are formed integral withthe -plate 20, to which is secured a clamp 2l held in place by asuitable bolt 22. lVhen the pump is not in operation the same is heldbetween the "bars 1 and 2 as shown in Fig. 1, and conse- `qug'entl'y outof theway. When it is desired 'to operatethe pum the-same is movedpivotally to the dotte position. shown Fig. 1.05

thedball/fromthe pump and then it is operate v` l In arranging the pumpon the bars l and 2, (the same is preferably positioned so that the tube4 may veasily reach the valve 4, and also may be of such a length as to"be inserted in the tubular piston rodI 9. When the tube 4 is not inuse, as shown lin dotted lines in Fig. 1, a suitable cap is fitted overthe outer portion of thevalve 6^for protecting the same against theentrance of dirt and other foreign matter.

Having thus described my invention I claim as new` and desire to secureby Letters Patent l. In a device of the character described, a pumpstructure, a plurality of encircling fingers extending from the bottomthereof, said fingers being spaced a substantially equal distance apartand in a circle, a ball fitting into said fingers formed with an eX-vball extending from the lower clamping member, a pump structure havingits upper end removably positioned in said fingers,

and a plurality of clamping members engaging sald ball arranged at thelower end of said ump struct-ure.

3. n a device of -the character described, the combination with abicycle frame, of a pump structure, means for universally journaling thelower end of said pump structure to one of thelower bars of said frame,.and means for removably connecting the upper end of said pump structureto one of the upper bars of said frame, said means including a pluralityof resilient fingers arranged substantially in a circle havingoverlapping projections for engaging the upper end of' said pumpstructure.

In testimony whereof I have signed my name to this specification in thepresence of two subscribin witnesses.
